Custom Web Part in Portal Engine using Kentico 10

Hi,

Do you see any (script) errors on the page or in the Event log module? Could you share the code before and code behind of your Web Part?

You can also look at the default Kentico Web Parts, the code can be found in [your installation Path]\CMS\CMSWebParts\ Although they might be a bit more advanced.

Hi Bhadresh,

Do you have code like this in .ascx file:

<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />

And in .ascx.cs:

protected void Button1_Click(object sender, EventArgs e)
{
    //do stuff
}

You can check event log also, maybe button click is triggered but something else cause error.

Best regards, Dragoljub

@David, @Dragoljub Ilic I check with the code and event log, But I can't find any error. Using the ASPX Blank web template this custom webpart working fine. But when I checked with my portal engine webtemplate site button click event not trigger.

Please review below my code Helloworld.ascx

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="HelloWorld.ascx.cs" CodeFile="~/CMSWebParts/MyWebParts/HelloWorld.ascx.cs" Inherits="CMSApp.CMSWebParts.MyWebParts.CMSWebParts_MyWebParts_HelloWorld" %> <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
<asp:Label ID="Label1" runat="server" Text="Label" />

Helloworld.ascx.cs

public partial class CMSWebParts_MyWebParts_HelloWorld : CMSAbstractWebPart {

    protected void Page_Load(object sender, EventArgs e)
    {
        Button1.Text = DataHelper.GetNotEmpty(GetValue("ButtonText"), "Show time");
    }

    protected void Button1_Click(object sender, EventArgs e)
    {
        Label1.Text = DateTime.Now.ToString();
        Label1.Visible = true;
    }
}

Since you are using the codebehind, make sure you compile your entire application. If you are would be developing a website (vs application), you could change codebehind to "codefile".

@Bhadresh: Please update your code with below code snippet

public partial class CMSWebParts_aspx_DemoASPXWebPart : CMSAbstractWebPart
{
    #region "Properties"



    #endregion


    #region "Methods"

    /// <summary>
    /// Content loaded event handler.
    /// </summary>
    public override void OnContentLoaded()
    {
        base.OnContentLoaded();
        SetupControl();
    }
    /// <summary>
    /// Initializes the control properties.
    /// </summary>
    protected void SetupControl()
    {
        if (this.StopProcessing)
        {
            // Do not process
        }
        else
        {
            Label1.Visible = false;
        }
    }


    /// <summary>
    /// Reloads the control data.
    /// </summary>
    public override void ReloadData()
    {
        base.ReloadData();

        SetupControl();
    }

    #endregion

    protected void Button1_Click(object sender, EventArgs e)
    {
        Label1.Text = DateTime.Now.ToString();
        Label1.Visible = true;
    }
}

I hope this will help you.

Thank you for the comments @Vasu : I tried with the Same but seems Click event is not trigger. page load event is executed but button click event is not trigger.

Can you check if a default Kentico Web Part works?

@David

Yes other inbuild web parts working fine.

Even created Custom web part working fine in ASPX Blank Web template.

@Bhadresh

I have done sample in my local the following steps and its working fine.

1. Created custom web part from Application->Web Parts
2. Added above code snippet from Visual studio
3. Drag and Drop this web part into root.aspx design mode. Template location is CMSTemplates->BlankSiteASPX
4. Tested from CMSDesk and its triggered the button click event.

Note: You can also debug your code to enable debug=true in web.config

Please let me know, where actually this code is been used?

Did the comment from Dave help or make sense to you?

Did you setup a website or webapplication project? (devnet.kentico.com/...web-app-vs-website-which-one-is-best)

Yes David, That I did but not work.

I created the Site with Sample blank web site in Web Application project. I did with all above comments but not work.

Can you just export the Web Part from Kentico:

This will create a .zip which also includes the code files.

@All

I found the cause that with Master Template. When I remove the Master Template From root level, itw working fine. with Master Template button trigger not executed. Is any idea what the cause in Master Template.

Is it a custom master template? Any other Web Parts or scripts on it?

@David,

Yes, It is the custom Master Template and used the Web Part zones. I define the links foe the css and scripts.
